Since you asked so nicely for a critique, I'll see what I can do.

Your overall picture is very good, the proportions are all what they should be, the hair looks really nice and you've done a good job defining the muscles.

Now, that said there are a few things that stand out to me. His elbow is much to sharp, especially from an outside angle. The sharp angle of the elbow is on the inside edge that sits by the ribs, the outside edge that can be seen in the picture is (usually) fairly blunt and rounded.

Also, his bicep on the same arm is a little too short. Lengthen it in the direction of his shoulder some and it should be fine.

Lastly, his collarbones aren't placed quite right either. I'd move them just a little so that the medial ends by his neck match up with the line running up his abs.

Hope that helps. Keep up the good work, it's really fun to see.

that was an excellent critique! :D very helpful ^^

No problem, I like to help when I can and critiques are a good way to do that. Didn't expect a reply quite so soon after though.

That's lucky, for a moment I thought maybe you were like me and lived on the internet, which is good and bad in it's own little way.
